摘要

通过搭建可视化试验台观测了重力场中水平金属纤维表面的液滴形状，并测量了液滴形状参数，包括液滴直径、高度、接触角、接触线宽度和接触线高度。通过拟合参数关联式，求解了液滴固-液界面子模型和气-液界面子模型的描述方程，开发了一种椭球形的纤维液滴形状模型。液滴模型的轮廓预测结果和观测试验得到的液滴图像吻合度较好，可以在±10％的误差范围内描述98%的试验结果，平均偏差为4.6％。

Abstract

The study observed the shape of the droplet on the surface of the horizontal metal fiber in the gravity field by building a visual test bench. The geometry parameters including droplet diameter

height

contact angle

width of contact line and height of contact line were measured. By fitting the correlations of these geometry parameters

the description equations of solid-liquid interface and gas-liquid interface were solved and an ellipsoidal droplet shape model on metal fiber was developed. The predicted shapes of droplet model are in good agreement with the droplet images obtained from the observation experiment. The predicted results can describe 98% of the experimental results within the deviation limit of ±10%

and the mean deviation is 4.6%.
